This time, we're super pumped to have Gregory McCubbin from Dapp University join our Dev Community AMA Ep.3 and we're going to build dapps together!  We will be discussing creating blockchain applications with Ethereum, Web3.js, and Solidity smart contracts. If you are a developer who’s not familiar with how to develop on the blockchain or still get puzzled in the smart contract, this is the greatest opportunity for you to ask any technical questions!
